Application 111 a February 2, 1912f Serial a... 674,861.

T 0 all whom it may Cohen-n:

7 Be it known that I, LUTHER K. SMITH, a citizen of the United States, reslding 1n Moberly, in the county of Randolph and State of Missouri, have invented certain new and useful Improvements in Journal-Boxes,

of which the following is a specification.

. My inventionrelates to journal boxesespecially adapted to the journals of locomotive driving wheels and other semi-heavy journals, and has for its object to produce new and improved means for taking up the Wear between the journal boxand the pedestal jaws and to hold the box against lateral. movement. The said devices are illustrated in this application in connection with a journal bearing of the character of that illustrated in Patent -No. 941,661, issued to me November 30th, 1909, but theyare not confinedjn use to a journal bearingof this description.

My object is to provide a structure which shall be simple in construction and shall be economical and durable in use, and a most important object to be accomplished is that the parts mentioned which require adjustment and replacement in use may be so adjusted or replaced without dismantling a locomotive engine, if they are applied thereto, or sending the same to the repair shop,

whereby usefulness of the engine is greatly increased.

In achieving the foregoing objects, my invention. consists in the production of means for taking up the wear between the journal bearing and :the pedestal jaws comprising a wedge which can be adjusted to compensate for such wear Without dismantling the engine, in combination with a liner and means for holding the latter against displacement.

In the accompanying drawings illustratlng a desirable form in which my inventlon.

may be embodied,-Figure 1 is a face view of a journal bearing embodying my invention. Fig. 2 is a vertical section thereof on the line 22, Fig. 1, looking toward the right. F ig.

I have illustrated my invention as applied to a construction such as that shown in my said Patent No.941,661, wherein the truck frame or pedestal A has jaws a a which are connected at the bottom by a jaw binder (1 Between the jaws a a, and adapted to slide vertically therein is mounteda journal box B. This comprises a body member I) which is .of inverted U-shape open at the bottom, and is provided with a removable brass li' and cellar block 6 brass are beveled transversely as indicated at 6 and the upper edges of the cellar block are similarly beveled. The meeting edges of the brass and cellar block are also beveled longitudinally, as indicated by dotted line m in Fig. 2, whereby'the cellar block is adapted-to lock the brass place, as indicated in my said patent. F langes w hold the brass in place against further movement forb upon the cellar block, whereby the cellarblock is held in place and provides ajbrace to hold the sides of the body member together, and prevent its separating or break: ing. The body member 6' has a lubricant reservoir 5 into which lubrica'ntmay be inserted through opening 12 closed by a bolt 6". Another opening 6 is provided closed by a similar bolt 5. Through this theair may escape while the lubricant is being inserted .and these openings are adapted to permit the insertion of an instrument to ascertain the amount of lubricantin the reservoir 6. Channels 6" conduct the lubricant from the reservoir 6 to the bearing and to longitudinal distributing channels b. Reservoirs b may receive lubricant and .conduct the same-through ports b 'to lubricate shoe b and the adjustable wearing dev-ices on the opposite face which will be hereinafter described. The ports b, Figs.- 2, 3 andt,

movement. These means may be adjusted to take up the wear caused by friction, and to compensate therefor, so that notwithstandthereof is formed a flange c which extends throughout the length of the wedge and ing such wear the journal box will at all times be held against lateral movement. Such means as illustrated comprise a plurality of separable members which may be readily mounted upon and removed from the pedestal jaw. As illustrated, the devices provided for this purpose comprise a Wedge C illustrated in detail in Figs. 11, 12 and 13, and a plateD likewise illustrated in .detail in Figs. 14., 15 and 16. The wedge C is formed with a plane face 0 and-with a tapered face 0. Upon one longitudinal edge upon the opposite longitudinal edge is formed a short flange'c The plate D is provided upon one of its longitudinal edges with a flange (Z. The pedestal jaw a is formed with a recess Eupon its inner edge, and this recess is adapted to receive and snugly hold the plate D and prevent the said plate from moving up or down.

sheet liner F, Figs. 17 and 18, is provided which may be inserted between the plate D and the" pedestal jaw a to compensate forwear upon the sliding faces of the wedge C and the box wearing plate G when desired. The said plate G has a boss 9 by which it is held in a recess g of thebody portion 1).

A wedge bolt 0 has an enlarged head 03 which fits in a dove-tailed channel ha in said wedge C and forms the means whereby the wedge is adjusted up and down. This bolt passes through a hole inthe binder a Nuts 0 0 are threaded upon the said bolt, one on each side of a yoke 0" which is attached to the binder a and serve to movethe bolt up and down. In the use of my said adjustable wear take-up devices the wedge C is applied in position on the pedestal jaw, with the flange on, the wheel side. The wedge is lowered until the flange 0* is at its lowest point. The plate D is then inserted sidewise between the said wedge and the pedestal jaw a in such manner that its body portion (Z will pass between the wedge face 0 and the, inner face of the pedestal. jaw, and its flange d will engage the face of the pedestal jaw opposite the wheel and prevent the said plate from moving rearwardly. The wedge G is then forced upwardly by turning nut 0 down until the flange 0 passes above the said plate, whereupon the plate is securely held in position and prevented from moving forwardly by the said flange 0 and from moving .rearwardly by its flange d. The upper and lower walls of the pedestal recess E will prevent the movement of the said plate in a vertical direction. The said wedge C is preferablymade of cast steel whereby the breaking of the flanges is obviated. The said wedge forms one of the wearing faces exposed to the friction caused by. the vertical movement of the journal box. The other wearing face is the brass plate Gr which is held by its boss 9 in the body portion 6.

The sheet liner F is provided for use when required. To insert this the wedge C is forced down,'the plate D or wedge liner is removed, and the sheet liner F is inserted in position between the plateD and the pedestal jaw. This sheet liner cannot work up or down on account of the recess Ecut in the pedestal jaw, and it cannot work out against the wheel H, as it is held in place by the large flange c on the wedge, and cannot work out toward the inside of the engine as the flange d on the wedge liner or plate D prevents it. Thereby a frequent cause of objection to the use of such sheet liners due to their creeping out. of place is obviated.

An important advantage achieved by the construction above described is that by its use the wedge can be forced down in a few minutes by one man without taking the wedge out of the pedestal jaw or dismantling any part of the engine. I am not aware of any other construction which will permit the wedge to be relined without taking the wedge out of the jaws. To accomplish this the frame binder a must be 115 removed. 'It will be perceived that by my invention removal of the frame binder is unnecessary. 'j

Hub Zahara-In Figs. 6, 7 and 8 I have illustrated an improved hub liner devised by me; This is in two parts, which are the same in construction with the exception that they are made right and left. One of such hub liners is illustrated in detail in said figures, and is there lettered I. Said hub liners are made substantially-in the arc of a circle, and are provided with peripheral flanges 2' which are received in correspond ing grooves 11 in the body B. At the upper portion the end of the said grooves is closed by the body at i forming an abutment \vhiclf limits the upward movement of the hub liners. llach hub liner is provided with an inwardly projecting stud i which is received in a corresponding recess 2" of the body (see Fig. 3). The cellar block I) when moved to its extreme forward adjustn'ient passes beyond the said studs 11 and holds the hub liners in place. Fig. 2. The brass b likewise overlaps the inner edge of the hub liners alid assists in bolding them in place, and forms a support therefor. The wearing face i of the hub liner is formed of a plate of suitable hearing metal. such as tin, properly fixed thereto and this maybe renewed when desired. Said hub liner possesses particular advantages in that the hub liner can be removed for the purpose of repairing or refacing the bearing face without taking the journal box off from the journal or out from under the engine. only necessary to pull the cellar block b and the journal brass 7) out of the box far enough to clear the inside face of the liner and the studs 2', whereupon the said hub liners may easily be removed by simply sliding them out of the grooves 2''. It is not necessary to dismantle any part of the engine in order to accomplish this purpose. The hub liner herein described and illustrated is not claimed in this application, but is claimed in a divisional application Serial No. (592,671 filed April 1912.

(r'rmse /z0Z/Zer.-'lhe said grease holder consists of a plate J which is curved transversely to correspond to the curvature 'of the journal. It is provided with longitudinal flanges which are adapted to slide freely under the projecting edges of the .brass 7) as shown at 7' (Fig. 1). The obect of the said over-hanging flanges is to catch all of the grease that comes from the top of the journal. The concave side of the said grease holder J is formed with the same curvature as the journal to cause a film of pure grease to be held against the journal at all times, and this also forms a dust guard preventing any foreign substances from gettin on the journal. Upon the under side of he said grease holder J are formed two dowel pins 7' which form a guide for two helical springs j and serve to hold the said springs in place. The two springs have seats in recesses y" in a sliding key j. These springs serve to hold the rease holder against'the journal and also hold the said grease holder key 7' in the cellar block. The said key serves the purpose of holding the dust guard in place and of permitting its removal when desired. For this reason it has a shoulder j on its To remove the hub liner it is under side. The said key is received in a recess j in the cellar block, and the said recess j has a corresponding shoulder j. The key is provided with an opening 7' in its end to permit. the insertioi'l of a tool for the purpose of removing the same. \Vhen it is desired to remove the grease holder a tool is inserted in the opening j" and the said key is lifted, thereby clearing the shoulder j and compressing the springs j, so that the dowels j will, pass into recesses j. 'lhereupon the key may easily be slid outv of place, carrying with it the grease holder. The said parts are so adjusted preferably that the dowels shall at all times be con tained within the recesses j whereby the grease holder is held in proper position.

The "said grease holder presents an important advantage in that it does not touch the journal and thereby no friction ensues. Further that it preserves a thin film of pure grease between the journal and the sheet at all times, and that it is absolutely dustproof. The said grease holder and dust guard is not claimed in this application but is claimed in a divisional application filed April 23, 1912, Serial No. ($92,672.

While I have described with great particularity the detail features of construction of the said invention, it will be a 'iparent that the invention is not in all things limited to such particular details or structural formation, and that equivalent devices may be employed and changes made therein within the limits of the appended claims.
